Truck is leaning to the left?

I have a 2000 Ford F-150 and would like to know the possible reasons it's leaning to the left. I've replace all four shocks and put in a flip kit. I'll be replacing the coil springs but if that doesn't fix the problem I would like to know where I should look next.

Ford 2001 F-150 XLT won't start with new battery?

A few days ago I learned my battery was bad so I bought a new one. I installed it and suddenly my truck won't start. I had been able to jump it with the old battery but now it won't even do that. It will crank but will not start. I have checked the inertia switch which was pressed down. I don't have the equipment to check the fuel pump or the pressure in the line. Is there anything else I can check on before I have it towed and pay a bunch of money to a mechanic to look at it?

1990 Ford F-150 won't start?

I'm looking at a 1990 f150 with the dual tanks and has an 4.9l inline 6. The guy said he replaced the radiator, distributer, water pump, fuel pump, starter, plugs, and injectors. He said last time he drove it he said it wouldn't start. But the motor will turn over. He said the starter quit working but he has a warranty on that and the distributer if those are causing the problem. He wants 1500 for it but I don't want to get it and it ends up being a 500 dollar repair. I read somewhere in a forum someone who had a similar issue and it ended up being the fuel tank selector switch. I want someone's input on what it might be?! Any help is appreciated thanks!

2007 F150 cranks but won't start?

I have a 2007 Ford F150 5.4 4x4 that sometimes will crank but won't start. The last time it has done this it has been about 30 degrees and It only acts up when it is cooler. 99 times out of 100 it will start no problem. I've replaced the fuel pump relay and I can hear the pump when I turn the key. What could be causing this? It has 100,500 miles on it.
